Jeremy, congrats on owning your reading! I'd recently seen your note about using reading.am, but I've been on holiday and not had a chance to get back to you.
In general it seems like you've found most of the salient pieces I liked about it. For the record these include:
* I like the idea of "bookmarking" everything I'm reading as I read it. Even for things I don't quite finish, I often will want to know what the thing was or how to easily find it at a later date.
* It has an easy to use desktop bookmarklet that makes the friction of using it negligible. (On mobile I use the ubiquitous sharing icon and use my account's custom email address to email links to my account which is quick enough too.)
* Its RSS feed is useful (as you've discovered), but I've integrated it into my WordPress site using IFTTT.com for porting the data I want over. In my case I typically save the post as a draft and don't publicly publish everything that my lesser followed reading.am account does. Generally once a day I'll look at drafts to add some notes if necessary, or do some follow up reading/research (especially when I've read something interesting via mobile and didn't have the time), and then publish a subsection of the captured reads as public.
I've filed an issue with the developer to see if he'd include the comment data within Reading.am into the RSS feed so that it could be included in the passed data, so that when commenting there, the commentary could also be passed across to my site as well.
While I typically prefer to default to POSSE when I can, this PESOS workflow is generally acceptable to me because it required very little effort and I like having the drafts to determine which I should post publicly/privately as well as for a nudge on potential follow up for some of what I've read.
One other small thing I had done was (via plugin) to have any links on my site auto-post to the WayBackMachine on archive.org as I read/post them that way there's a back up version of what I'd read so that in the future copies are available even if the site goes down at a future date. I suspect you could do this with a simple POST call, an example of which I think is documented in the wiki.
As a subtle tweak you may wish to take a look at https:/
I know you're always saying that you're not a developer, but you've puzzled out a regex filter, implemented it, and posted it to your site for others to benefit. I would submit that you could now proudly wear the title even if you have no intention to do it professionally. Neither of us may be at the level of people like aaronpk or snarfed, but then, really, who is?
I also love that you've got a Webmention form set up, working, and looking great. Congratulations! If you want a small challenge, perhaps you could massage it to create a Grav plugin so others could easily implement it? If you want less challenge (and obligation for support), perhaps submit what you've got as an issue to the Grav Webemention plugin https:/
Congratulations again Mr. Developer!
